A study on America Police-Private Security Partnership in Business Improvement Districts, Special Event Safety and Security, Community Policing, Alarms, Investigations, Electronic and Financial Crimes Investigations. Many Police-Private Security Partnerships have significantly changed how policing is done with respect to field operations, particularly patrol and access control. Some areas in which these collaborations have produced notable results are described here.

In this paper,we implement the Audit Trail Service Sydtem for the EDI Security.It has solved a law dispute between enterprises by informations that have generated by the EDI serice systrm.The audit trail service sys-tem implemented for EDI security satisfied the requirements of audit and the protocol of the security serive of X.435 and X.400.The EDI Security Audit System consists of the event discrimiator,the audit recirder,the audit archiver,and the provider of audit services .The event discriminator classified the reansmitted data from the EDI network ot audit sercices.The audit recorder constructs an index that has combined time information wiht audit unformations which are classified by the event discriminator.ZThe audit archiver performas the vacumming of added audit imformations by passing time by passing time.The audit provider is a module that carries out the audit trail servies by using stored audit informations. The audit provider suports audit servies,which are non-requdiation,proof and probe,controller of security,and accesing infrimation.The audit trail service system for EDI security constructs audit information by using index that is combining time imfromation,so it supports especially fast accesing audit information.

This paper presents the design and development of network for housing estate security system. The system can cover up to 961 houses which can be up to 1,200 meters long transfer rate of 9,600 bps. This system uses checking and warning the abnormal situation. More over this system has ability to control switch on/off the electrical equipment in the house via AC line control system. The system consists of 4 parts. The first part is a security system of each house using MCS-51 microcontroller as a central processing unit scan 32 sensors and control 8 appliances and send alarm. The MCS-51 microcontroller received control signal via telephone used DTMF circuit. The second part is distributed two levels master/slave network implementing after RS-485 serial communication standard. The protocol its base on the OSI (Open Systems Interconnection) 7 layers protocol model design focus on speed, reliability and security of data that is transferred. The network security using encrypt by DES algorithm, message sequence, time stamp checking and authentication system when user to access and when connect new device to this system. Flow control in system is Poll/Select and Stop-and-Wait method. The third part is central server that using microcomputer which its main function are storing event data into database and can check history event. The final part is internet system which users can access their own homes via the Internet. This web service is based on a combination of SOAP, HTTP and TCP/IP protocols. Messages are exchanged using XML format [6]. In order to save the number of IP address, the system uses 1 IP address for the whole village in which all homes and appliance in this village are addressed using internal identification numbers. This proposed system gives the data transfer accuracy over 99.8% and maximum polling time is 1,120 ms.

Since simple and convenient user interface, the Web is diffused widely. For integrating Web as a view of user interface and CORBA, CORBA object is made in applet, which is sent to Web browser in Client and executes by Web browser. To use CORBA Event Service in Web without violating a security constrains of applet, we need a interoperability of Event Service. This paper investigates interoperability of event channels of the event service of CORBA. We present three different methods that make one event channel. Pros and cons of each method are described. All mentioned approaches have been implemented in Java. An experimental performance evaluation has been carried out and evaluation results are also given.

As the importance and the need for network security are increased, many organizations use the various security systems. They enable to construct the consistent integrated security environment by sharing the network vulnerable information among IDS (Intrusion Detection System), firewall and vulnerable scanner. The multiple IDSes coordinate by sharing attacker's information for the effective detection of the intrusion is the effective method for improving the intrusion detection performance. The system which uses BBA (Blackboard Architecture) for the information sharing can be easily expanded by adding new agents and increasing the number of BB (Blackboard) levels. Moreover the subdivided levels of blackboard enhance the sensitivity of the intrusion detection. For the simulation, security models are constructed based on the DEVS (Discrete Event system Specification) formalism. The intrusion detection agent uses the ES (Expert System). The intrusion detection system detects the intrusions using the blackboard and the firewall responses to these detection information.

FinTech has expanded to the extent that not only businesses but almost everyone can feel the impact. The spread of the scope of use has introduced a variety of new financial services that are changing the way we live. In these environments, it is important to develop reliable security measures to protect against cyber attacks. The number of mobile financial transactions in the financial sector is also increasing, making security vulnerable. In this study, we studied security through mutual authentication method that can safely handle financial security and focused on FinTech's security processing through multi-party mutual authentication method that strongly prevents leakage of information even in the event of continuous and sophisticated attacks.

As digital evidence has a highly influential role in proving the innocence of suspects, methods for integrity verification of such digital evidence have become essential in the digital forensic field. Most surveillance camera systems are not equipped with proper built-in integrity protection functions. Because digital forgery techniques are becoming increasingly sophisticated, manually determining whether digital content has been falsified is becoming extremely difficult for investigators. Hence, systematic approaches to forensic integrity verification are essential for ascertaining truth or falsehood. We propose an integrity determination method that utilizes the structure of the video content in a Video Event Data Recorder (VEDR). The proposed method identifies the difference in frame index fields between a forged file and an original file. Experiments conducted using real VEDRs in the market and video files forged by a video editing tool demonstrate that the proposed integrity verification scheme can detect broken integrity in video content.
